Am I in Trouble?

Hi,

Troubleshooting....

Am I in trouble?

I'm only a mechanical engineer, no electronics guy, so perhaps someone else can help me.

Something weird here, just found out my printer can act as a generator aswell.

No cables hooked up, moving a steppermotor lights up the ulticontroller display and thermo prints led's. Something wrong with the electronics, or/and can you damage them when moving the steppermotors by hand?

Another thing is, is it possible and easy to come up with something to shut down the usb when the printer power switch is off? Led's are on and the electorinics fan keeps running (slowly).

Another other thing- Is there a USB problem with my computer, or something in cura?

In cura 13.04 i can run a print by the usb cable, but in later versions i can only control the printer but it willl not print.

Regards

Kees

Hi

There's nothing wrong with your printer, that's normal. I blew a stepper driver once after I had been vigorously moving the hot end by hand. I'm fairly sure this caused it. So I don't move mine around by hand too quick anymore.

It's normal. I move my head around all the time but I also don't move it fast and now I will know to not do it too much - give the stepper driver a few seconds to cool down.

I better be careful
